Overview

geoPlugin is a free IP geolocation API that also includes real-time currency conversion data alongside the location information. It identifies a visitor country, city, and local currency from their IP address without requiring any API key or registration. This makes it one of the simplest APIs to add to any web project.

💡

Beginner Tip

Passing no IP to the endpoint automatically looks up the requester IP, and the response includes currency data — so you can localize both language and pricing in a single API call.

Available Data

Common Errors & Troubleshooting

geoplugin_status: 404 The IP address provided was not found in the database.
✓ Check that the IP is a valid public IPv4 address. Private IPs (192.168.x.x, 10.x.x.x) will not resolve to a location.
Empty currency fields The detected country may not have currency data available.
✓ Fall back to a default currency (e.g. USD) if geoplugin_currencyCode returns an empty string.
Mixed HTTP/HTTPS content warning The geoPlugin base URL uses HTTP, which browsers flag when used on HTTPS pages.
✓ Call the API from your server backend and relay the response to the frontend to avoid browser security warnings.
